SPECiPICATION forming part of Letters Patent No. 382,394, dated May 8,1888.

Application filed August 20, 1887. Serial No. 247,409. (No model.)

To aZZ whom, it may concern:

Be it known that I, J onN B. SUTHERLAND, a citizen of the UnitedStates,resicling at Detroit, in the county of Wayne and State ofMichigan, have invented certain-new and useful Improvements in Railways;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which itappertains to make and use thesame,reference being had tothe accompany ing drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention relates to metallic railway-ties and to the attachment ofthe rail thereto.

The object of this invention is to provide at moderate cost a durabletrack and one in which the rails will be provided with a seat having therequisite flexibility.

"The essential features of my invention will be fully described in thefollowing specification,and particularly pointed out in the claims.

In the accompanying drawings, forming a part of the specification,Figure l is a perspective view of a railway-track section embodying myinvention. Fig. 2 is a side elevation of a portion of my device, showingan end view of the chair in position thereto. Fig. 3shows an end view ofmy metallic tie. Fig. at is an enlarged perspective view of my device,showing a modification in its construction; and Fig. 5 is an invertedplan view of the metallic chair.

A represents my improved tie, which I preferably form out of a singlepiece of sheet-steel and in the shape shown, this latter being obtainedby first doubling the plate on itself on its central line to form therigid web a, by means of which the tie is adapted to be anchored in theballast of the road. On each side of this web a the plate extends out ona concavo convex plane, as shown, to form the U shaped shoulders I) b,which constitute the body proper of the tie. These shoulders give to thesupport the flexibility required to counteract the pounding of thewheels on the rail to secure to the tie suflicient strength in itssupporting parts withoutimpairingtheir flexi bility. A vertical flange,c, is formed in each of the opposing edges of the plates, as shown. a. aare bolt-holes which serve to fasten the tie to its companion parts,hereinafter described.

13 is the rail-chair, which consists of a metal plate having flanges d(2 formed along the edges of its upper face and the grooves e 6 cut outacross its under face.

ff are bolt-holes which are made to corre spond with the holes a a inthe tie. The upper edges of the flanges (Z cl are made to embrace thebase of the rail B, and between the lower face of said rail base and theupper face of the chair B a cushion, O, of wood, papiermach, or anyother flexible material, is insorted to break the pounding of the wheelsat the connecting-points, as well as to deaden the noise. The grooves ee are adapted to receive the flanges c c of the tie. g g are bolts bymeans of which the parts are connected to gether. They are made with ahead lapping on the side of the rail, as usual, and with a thread ontheir lower end. The nuts h h complete the fastenings.

Between the tie A and the chair B may be interposed an additionalcushion, D, which consists of a layer of tarred paper, or any other likematerial, which is perforated at suitable points for the passage of thebolts 9 g, which serve to retain the said cushion in position.

In Fig. 4. is shown a modified form of my improved metal tie. Thisconsists in inserting in the tie as formed as above, and at the pointsofattachment of the rails thereon, a C- spring, A, shaped so as to conformclosely to the under face of the tie-body. These springs are adapted tobe held in place in the tie by confining them between the bolts 99,fastening the chair to the tie. This modification allows of the use of alighter plate in the construction of the tie A, which the springs A arede signed to re enforce at the points of greatest resistance.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In combination with a metallic tie having a rigid web and lateralflexible wings pro vided with strengthening flanges on their edges, ametallic chair having flanges d d, grooves e e, and holes f f, the railIt, the cushion G, the bolts g g, and nuts h h, substantially as and forthe purposes set forth.
